Problems solved by technology

The thickness of the fireproof adhesive layer is easy to form a difference in thickness during the drying process, resulting in uneven surface of the fireproof adhesive layer. Due to the limitations of its own viscosity, leveling and other factors, the existing lamination liquid cannot make up for this defect; at the same time, the existing lamination liquid itself is easy to The generation of bubbles will easily lead to a large number of microbubbles in the interlayer. The existence of microbubbles reduces the actual fireproof effect of the composite fireproof glass fireproof glue, and leads to poor apparent quality of the composite fireproof glass, and the hardness of the fireproof layer is not enough, which seriously affects the composite fireproof glass. The use effect and service life

Abstract

The invention relates to composite fire-resistant glass combination liquid and a preparation method thereof as well as composite fire-resistant glass and belongs to the field of safety glass. The composite fire-resistant glass combination liquid comprises the following materials in parts by weight: 25-150 parts of potash water glass, 100 parts of deionized water, 0.2-1 parts of char forming agent, 0.1-0.5 parts of char forming additive, 0.01-0.05 parts of defoaming agent, 0.1-0.2 parts of plasticizer, 0.1-0.2 parts of flattening agent and 0.1-0.5 parts of cross-linking agent. The composite fire-resistant glass combination liquid has the advantages that the synergistic effect is generated among the components of the combination liquid by improving the formula of the combination liquid, bubbles in the interlayers of the composite fire-resistant glass are eliminated, and the high-performance non-microbubble composite fire-resistant glass with the transmittance of 82%-83% and the fire-resistance time up to 95 minutes is prepared.

Description

technical field [0001] The invention belongs to the field of safety glass, and in particular relates to a lamination liquid for composite fireproof glass, a preparation method of the lamination liquid and composite fireproof glass laminated by the lamination liquid. Background technique [0002] Fire-resistant glass is a kind of high-end architectural glass. In addition to some properties of ordinary glass, it also has the properties of controlling fire spread, smoke insulation and heat insulation. Fireproof glass is divided into composite fireproof glass and single piece fireproof glass. At present, composite fireproof glass consists of two or more pieces of flat glass and a fireproof adhesive layer sandwiched between the flat glasses. When encountering a fire, the fireproof adhesive layer absorbs a large amount of heat generated by the fire, rapidly foams and expands, and forms a heat-insulating fire-resistant and heat-insulating foam layer. At the same time, the fireproo...
